java實(shí)現(xiàn)簡(jiǎn)單的圖書銷售統(tǒng)計(jì)系統(tǒng)，要用GUI 求java高手幫忙 謝謝啦

我看到數(shù)據(jù)好像是保存在文件中的，這樣解析很不給力。

創(chuàng)新互聯(lián)是一家業(yè)務(wù)范圍包括IDC托管業(yè)務(wù),雅安服務(wù)器托管、主機(jī)租用、主機(jī)托管，四川、重慶、廣東電信服務(wù)器租用,BGP機(jī)房服務(wù)器托管，成都網(wǎng)通服務(wù)器托管,成都服務(wù)器租用,業(yè)務(wù)范圍遍及中國(guó)大陸、港澳臺(tái)以及歐美等多個(gè)國(guó)家及地區(qū)的互聯(lián)網(wǎng)數(shù)據(jù)服務(wù)公司。

建議使用 access 數(shù)據(jù)庫(kù)，小巧又好用。

其他的這幾個(gè)功能也不難仔明，樓主，你哪擾皮里不會(huì)，你的思路是緩戚差什么，可以講一講，可以協(xié)助你完成。

java作業(yè)：利用所學(xué)的Swing控件，及不同的事件處理接口，設(shè)計(jì)一個(gè)書店收銀系統(tǒng)界面。 我要的是代碼。。。

真像樓上說(shuō)的，15分如果手頭上沒現(xiàn)成的代碼，是不會(huì)給你寫的。

java圖書館系統(tǒng)怎么看代碼看數(shù)據(jù)庫(kù)的信息

點(diǎn)擊電腦的開始。

首先點(diǎn)擊電腦的開始，找到QLServer配置管擾扒理器，將SQLServer網(wǎng)絡(luò)配置中的SQLEXPRESS的協(xié)議如下圖中的三孫滾個(gè)服務(wù)改為啟用，然后點(diǎn)擊TCPIP協(xié)議，修改動(dòng)態(tài)端口為1433，重啟服務(wù)器才能生效，首先建立一個(gè)java項(xiàng)目，命名為TestDB然后右鍵點(diǎn)擊TestDB選擇buildpath然后找到AddExternalJARs，找到下載的sqljdbc的包，打開即可，然后項(xiàng)目則李余的referencedlibraries目錄下能看到導(dǎo)入的包，新建一個(gè)包database包中再建立TestConect執(zhí)行以下代碼，代碼執(zhí)行結(jié)果和數(shù)據(jù)庫(kù)中查詢的結(jié)果一樣。
